Frequently Asked Questions

Product-specific compatibility, application, installation, commissioning and ordering guidance for 6ES5955-3NC41

Which SIMATIC S5 racks use this power supply?

The 6ES5955-3NC41 is specified for S5-135U and S5-155U central controllers and for 183U/185U expansion units.

Which main electrical ratings must match?

Verify 24 V DC input and the 5 V DC, 18 A main output before replacing the existing PS955.

How should the rack be made safe for replacement?

Switch off and isolate the incoming 24 V DC supply, confirm the rack is de-energized and follow the SIMATIC S5 removal sequence.

Which load checks belong in commissioning?

Measure the 5 V rail, confirm total rack current remains within 18 A and check all CPU and I/O status indicators after startup.

Can a later PS955 revision be installed without review?

Do not assume interchangeability; compare the complete MLFB, connector arrangement, rack type and documented output circuits.

Which migration information should be recorded?

Document the central or expansion rack type, installed CPU, module load, wiring, fuse arrangement and existing power-supply label.

Which order data should accompany the request?

Provide 6ES5955-3NC41, rack type, input voltage, required quantity and clear photos of the front label and connectors.
